Commercial production of sewer tubes with Betolar's Geoprime® solution has started in Belgium. Installation of sewer tubes made of alkali-activated concrete material (AAM) based on Betolar's Geoprime solution has started at one of Aquafin's sewer projects in Duffel, Belgium. The tubes are manufactured by Betolar's partner Tubobel Group.

The Belgian concrete manufacturer Tubobel Group, together with Betolar, has developed a sewer tube suitable for the needs of the Belgian market. Betolar's Geoprime solution is a climate-friendly alternative to cement. Aquafin installs approximately 200 kilometres of tubes annually in Flanders region.

Rainwater sewers are installed to store, infiltrate or transport rainwater, and they are commonly made of concrete. Wastewater sewers are installed to transport domestic wastewater from municipal sewers to a wastewater treatment plant. Wastewater sewer tubes are currently made of plastic, glazed clay or concrete.

Developing a new material solution has required the involvement of the entire value chain. Tubobel has developed sewer tube production together with Betolar's experts. Aquafin, owned by the regional government, has offered the first construction project in Belgium.

The building contractor has been the construction group BESIX, which operates in the Benelux countries. Betolar and Tubobel signed a commercial agreement last spring.
